Md. 1 Current
feed value
•
The current position is stored.
Update timing: 1ms for QD70P4

•
On completion of OPR control, the OP address is
stored.
•
Under speed control of speed-position switching
control, whether the current feed value is
updated or not or cleared to zero can be selected
by parameter setting.
•
The software stroke limit can be activated by
parameter setting.
•
If the current value has been changed by the
current value change function, the new value is
stored.

•
At an OPR control start, "0" is stored.
•
After an OPR control start, the movement
amount from near-point dog ON up to OPR
control completion is stored.
(Movement amount: Indicates the movement
amount up to completion of OPR control when
near-point dog ON is defined as "0".

Md. 5 Axis error
code
At axis error occurrence, the error code
corresponding to the error definition is stored.
•
If another error occurs during axis error
occurrence, the latest error code is ignored.
However, if a system-affecting error (error code:
800 to 840) has occurred, the old error code is
overwritten by the newest error code, which is
stored.
•
The error codes 800 to 840 are stored into Md. 5
for all axes.
•
When " Cd. 1 Axis error reset" (axis control data)
of the corresponding axis is turned ON, the axis
error code is cleared (to zero).
(Refer to "Section 13.2" for details of the error
codes.)
